Example of results from the demonstration function JHBDEMO. The bold solid line represents the measured pre-storm profile, the bold dash-dot-dash line the measured post-storm profile, the bold dashed line the predicted erosion profile (during storm impact prior to any post-storm recovery) from the MSBWT computer model for a storm surge given by the single dash-dot-dash line (in this case the storm surge level does not incliude effects of the dynamic setup which is computed suing additional considerations). The remaining line represents the crest elevation of the wave as alpha wave peaking over the longshore bar crest occurs and the wave reforms following bar-breaking.
